Spark plugs last from 80,000 to 100,000 miles before needing to be replaced.

I change my spark plugs every 100,000 miles which is every 5 years or so for me depending how much driving I do.

Replacing your spark plugs at the recommended intervals will help improve engine performance and gas mileage.

Best advise is to check your owner’s manual. As I know modern cars running unleaded gas can get around 100k miles on a set of plugs. Recently I replaces spark plugs on my Ford truck explorer 2013(110,000 miles). It is not easy to me, so I ordered new spark plugs online(link), and then went to the car service.
